Just had this thought as I’ve read about multiple GA accidents that resulted from unintentional flight into IMC with planes not equipped for it (no attitude indicator), resulting in disorientation and other things.
So, that said, would something low-tech like fuzzy dice, rosary beads, air freshener, etc. hanging from overhead help alleviate those issues if one unintentionally flew into those conditions? Help alleviate in this sense would mean help limit disorientation and assist in correcting pitch and/or roll in the absence of instruments.
